Whether you're taking a train, plane or private jet, the most obvious thing to wear when it comes to travelling has got to be a plain old tracksuit, right? Yes and no. Maya Jama, the very well-travelled host of Love Island, did once wear one to touch down in South Africa. But, styled with a lime green baby tee and some slimline black shades, the result was a degree more polished than your average sweatshirt and trackies combo, striking the perfect balance between comfortable and cool.
There are several ways to achieve a similarly elevated take on the dreaded 'l' word: loungewear. Lori Harvey's trick to turning that particular genre of clothing into a chic proposition is to throw on a trophy jacket, adding some look-at-me factor to an otherwise oh-so-comfortable outfit. Bella Hadid, meanwhile, lends polish to her leggings with sleek ballet flats (seek out a soft leather pair so they'll be gentle on swollen ankles).
Speaking of swollen ankles, there are a couple of in-flight essentials that you might want to add to your carry-on luggage so that you can guarantee your travel outfit covers all eventualities. Falke's Vitalizer Women Knee-High Socks actively support blood circulation through defined compression, making them an ideal companion if you're flying long-haul and don't want to arrive with swollen or heavy legs. If you tend to get cold when you're flying - or taking the train, for that matter - Rise & Fall's Finest Cashmere Scarf, available in 13 delectable shades, is big enough to wrap around the top half of your body or your legs for an added layer of warmth. And as well as loungewear, clothes with stretch will obviously be more comfortable than anything rigid like tailoring or denim.
Other excellent plus ones when you're on the move are onesies (Kim Kardashian thinks so anyway...), baby tees, comfortable trainers and crease-free shirt dresses that are polished yet practical. If those two adjectives don't sum up the ideal travel outfit, I don't know what does. Keep scrolling to see exactly what you should bookmark for your next trip.
The Cult Sweatshirt
On the smash-hit promo trail for tennis movie Challengers, Zendaya has served oh-so-many style aces, including this sweatshirt, a nod to a certain slogan tee that her character sports.
www.loewe.com
Loewe's Jonathan Anderson designed the movie's costumes, hence why this sweatshirt version is now available to buy on the brand's website for £475.
www.cos.com
Pair your sweatshirt with utility cargo trousers that can help increase your hand luggage allowance like this pair from COS.
www.net-a-porter.com
Nike's Cortez debuted 50 years ago, with a retro appeal that's never felt more relevant for sneaker fans.
The Onesie
Kim Kardashian's version of athleisure is a scoop-neck onesie from SKIMS. Duh. Styled with trainers and a grey marl zip-up, my only concern is that your legs might catch a chill if it's a night flight. Her private jet is probably stocked with blankets so consider packing your own or an extra pair of sweatpants the next time you're flying.
skims.com
Kim Kardashian's exact onesie is sold out at the moment but her shapewear brand has plenty more all-in-ones to offer travellers. Available in three shades and nine sizes, this cotton-rib style will be so comfortable - even if you're in the upright position for hours on end.
www.schuh.co.uk
These New Balance trainers will become a staple of your travel (not to mention off-duty) wardrobe.
Nothing beats the warmth (not to mention softness) of cashmere when you're travelling long-haul. Alo Yoga's waffle zip hoodie will ensure you have a first-class flight even if you're sitting in economy.
The Trophy Jacket
If you want to be warm yet still look sharp on arrival, Lori Harvey's trophy jacket is the only flex you need to get on first name terms with - and pronto. Styled with a bodysuit and slides, it's the definition of low maintenance.
www.mytheresa.com
The Attico's wool bomber jacket is the trophy jacket that has a timeless energy that you'll return to, season after season. With its wool fabrication, and relaxed hood, it's also the chicest cover-up when you're cruising at 30,000 ft.
www.oysho.com
The shapewear fabric of these slit-flare trousers defines without restricting movement; perfect if you're heading out almost as soon as you reach your destination. They're also breathable and high-strength (aka, guaranteed to go the distance).
www.dunelondon.com
Dune's flat sandals are some of the best on the high street, including this fisherman's-esque pair complete with buckled ankle strap.
A Baby Tee
Maya Jama's cute tracksuit and baby tee combo is a great option if you're heading out shortly after arriving at the airport. Swap the hoodie for a blazer, the sweatpants for jeans and you're good to go. (The sunglasses can stay put.)
www.thereformation.com
Made of a stretch-rib fabric, Reformation's baby tee will be comfortable for the duration of your flight (while also being handy for pairing with denim cut-offs or slip-style skirts when you reach your destination).
pangaia.com
Pangaia's snap-button hoodie is probably the most comfortable jacket you'll ever wear - and ideal for throwing over your shoulders if the temperature drops on board.
pangaia.com
If you never take off your straight-leg jeans, simply transition to straight-leg track pants whenever you're travelling, like this pair from Pangaia.
Ballet Pumps
Even if you're travelling first-class, your feet can still swell up. It's a fact. So instead of wearing a constrictive pair of shoes that you'll struggle to put back on, why not try a soft pair of ballet pumps? Not only have they made a huge comeback thanks to balletcore, but they'll be much more forgiving than loafers or court heels (shudder).
www.arket.com
A smart alternative to sweatpants if you're travelling for work is a drawstring pair of cargo pants, like this twill style from Arket.
Soft leather ballet slippers are a chic and comfortable option when you're in flight mode.
www.thewhitecompany.com
If your ankles tend to get cold when travelling, it's always worth packing a warm pair of socks like these cashmere beauties from The White Company.
The Holdall
Kylie Jenner might take a glam approach to air travel - I think those might be thigh-high cargo boots - but she's still a practical girl at heart. That bedazzled holdall is the perfect size for a long weekend, no?
www.uk.rains.com
Rains is your one-stop-shop for rucksacks and rain gear but also has some affordable weekend holdalls that make great cabin bags.
www.toa.st
Toast's wool-cashmere cardigan is the perfect travelling companion.
www.net-a-porter.com
Aussie sleepwear, loungewear and daywear brand Deiji Studios, named after the daisy flower, makes wide-leg trousers that will feel like pyjamas but look perfectly chic.
www.fitflop.com
FitFlop's leather mules, available in three neutral shades that will go with everything in your wardrobe, come with this fashion editor's stamp of approval (I literally wear them with every outfit, rain or shine, home or away).
The Trainers
Didi Stone's bright white trainers were the perfect finishing touch to her tracksuit two-piece. Apart from sliders, I can't think of a more comfortable shoe to wear when you're feet might swell ever-so-slightly.
www.on.com
On's famously comfortable trainers get a new waterproof membrane for wet-weather protection when you're away on your travels.
www.endclothing.com
This linen co-ord is technically a pyjama set, but for hot-weather travelling, there's nothing cooler or more comfortable.
The Shirt Dress
When Andie MacDowell touched down at Nice Airport, she looked like she was heading straight to a lunch meeting in Cannes. If you're travelling for work, a non-crease shirt dress is a safe bet. Look for knitted options that won't get rumpled (even if you're sat in economy).
www.meandem.com
Me+Em cotton-sateen shirt dress will be comfortable on your journey - and impeccable on arrival.
www.harveynichols.com
A braided pair of sandals will be comfortable for weary feet but smart at the same time.
The Co-Ord
Arriving at the Cannes Film Festival, Laura Harrier wore a striped co-ord that definitely would have passed muster, with no switch-ups necessary, on La Croisette. Simple and sharp, especially styled with a white T-shirt, try it the next time you need to hit the ground running after a flight.
www.whistles.com
This limited-edition striped co-ord is oh-so-easy to wear, but also guaranteed to turn heads.
www.whistles.com
Impeccably sharp but super comfortable thanks to their cargo-like construction, Whistles has hit the nail on the head with these trousers.
